ABSTRACT:
The neghold assembly of the present invention is used in photographic printers which do not have an automatic film advance system. The neghold assembly includes a transport base, a top insert holder, first and second aperture insert plates which are held in the transport base and the top insert holder, and a handle which is connected to the top insert holder. The first and second aperture insert plates are a set which have mating apertures which correspond to the desired film size. When a different size film is to be used, another set of first and second aperture insert plates having the appropriate size apertures are inserted.
